It's a common practice to store some unique document id in the index. Examples include url, path, or database id.
Zend_Search_Lucene provides a termDocs()
method for retrieving documents containing specified terms.
This is more efficient than using the find() method:
<?php
// Retrieving documents with find() method using a query string
$query = $idFieldName . ':' . $docId;
$hits = $index->find($query);
foreach ($hits as $hit) {
$title = $hit->title;
$contents = $hit->contents;
...
}
...
// Retrieving documents with find() method using the query API
$term = new Zend_Search_Lucene_Index_Term($docId, $idFieldName);
$query = new Zend_Search_Lucene_Search_Query_Term($term);
$hits = $index->find($query);
foreach ($hits as $hit) {
$title = $hit->title;
$contents = $hit->contents;
...
}
...
// Retrieving documents with termDocs() method
$term = new Zend_Search_Lucene_Index_Term($docId, $idFieldName);
$docIds = $index->termDocs($term);
foreach ($docIds as $id) {
$doc = $index->getDocument($id);
$title = $doc->title;
$contents = $doc->contents;
...
}
